The neck may feel strangled due to thyroid disorders, such as hyperthyroidism, subacute thyroiditis, Hashimoto’s thyroiditis, thyroid nodules, thyroid cancer and so on. You should go to the hospital for a timely checkup of the thyroid gland to see if there is any disease. You can check thyroid function, i.e., T3, T4, TSH, to see if there are symptoms such as hyper- or hypothyroidism. An ultrasound of the thyroid gland is required to find out whether the lesions inside the thyroid gland are diffuse or nodular. If a nodule is found within the thyroid gland, the echogenicity, border, aspect ratio, presence of punctate calcification, and blood flow signal of the nodule should be further described to determine whether the nodule is benign or malignant. Small benign nodules can be followed up, but if the nodules are large and have symptoms of pressure, surgery is needed, and if thyroid cancer is suspected, radical thyroid cancer treatment is needed.
